Plasmodium vivax infection compromises reticulocyte stability.
Bibliographic record
Abstract
Abstract The structural integrity of the host red blood cell (RBC) must be maintained for propagation of Plasmodium spp. during the disease causing blood-stage of malaria infection. Plasmodium vivax infection is restricted to reticulocytes. To assess the impact of P. vivax infection on reticulocyte stability, we developed a flow cytometry-based assay capable of measuring osmotic stability within heterogeneous RBC populations. We found that P. vivax preferred young reticulocytes are more osmotically stable than older reticulocytes and normocytes, and P. vivax infection decreased reticulocyte stability to levels observed for RBC disorders that cause hemolytic anemia. Moreover, P. vivax reticulocyte destabilization was more significant than P. falciparum normocyte destabilization. Finally, we found that P. vivax new permeability pathways contribute to the decreased osmotic stability of infected-reticulocytes. These results reveal a key vulnerability of P. vivax that could be manipulated to yield both in vitro culture and novel therapeutics.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
